To Jl-,ZZ whom it may concern.-

Be it known that I, CONRAD WILMsEN, a

subject of the German Emperor, and a resition.

This invention relates to improvements in scouring-machines for woven fabrics as used especially in the i'inal treatment of silks and half-Silks for umbrellas.

The system of most of the scouring-machines consists therein that the scouringknife carriers make a swinging or circular motion and that the fabric to be treated lies on an elastic cushion arranged above or below the scouring-knife carriers, while the scourtened tol each arm.

ing-knives, in consequence of their swinging or circular motion imparted to them by their carriers, release the fabric temporarily, which is thereupon advanced by steps.

The scouring-knives in this invention are so distributed that two or several knives run close or immediately behind each other, and thus treat the fabric in close succession before it is released for the purpose of being moved on. As in this way the fabric is pressed each time by the foremost knife a ainst the elastic cushion, and thus stretche the following knives do their scouring and rubbing far more eectively than the first. The scouring action is thus considerably improved.

The accompanying drawings illustrate a scouring-machine provided with knife-carriers which turn round in acircle, and below the same an elastic cushion for the fabric.

Figure 1 is a cross-section, and Fig. 2 a front view, of the scouring-machine, showing only the front row of the knife-carriers. Fig. 3 shows the journals and driving device of the knife-carriers in a top view and partly in a longitudinal section. Fig. 4 gives, on an enlarged scale, a front view of a single knifecarrier and its connection with the drivingshaft 5 and Fig. 5 is a corresponding side view with a cross-section through the knifecarrier. Fig. 6 serves to better explain the invention. It shows two knife-carriers turning in a circle in opposite directions in their working position. Fig. 7 is a front view of a knife-carrier with four scouring-knives fas- Similar numerals refer to similar parts ,throughout the several views.

In the system of scouring-machines on which this construction is based an elastic cushion 10 rests on ledges 9, fastened to the frame 8 of the machine, which cushion serves as a support lor counter-pressure surface to the fabric 11 to be scoured. The cushion 10 may be formed by a box 13, covered with india-rubber or any other elastic and airtight material whose hollow interior communicates with a vessel 15 with compressed air through a eXible tube 14.

Above the cushion 10 are journaled a number of knife-carriers 16 in parts of the frame of the machine. The knife-carriers are distributed uniformly over the working surface. Fig. 3 shows twenty-four of these knife-carriers arranged in groups of eight around a common driving-shaft 17 in a manner that four knife-carriers 16 are in front of vand four knife-carriers 16 behind the driving-shaft 17. The knife-carriers sit loosely on cross-pins 18 of blocks 19, screwed to U-shaped ledges 20 and 21. The latter may be screwed at their ends to the journal-blocks 22 for the shafts 17 or fixed to them by other means. These j ournal-blocks 22 are in their turn fastened to the frame of the machine 8.

The knife-carriers 16 are, as shown in Figs. 4 and 5, composed of the hollow boss 23, the arm-cross or radial wings 24, and the scouring-knives 26 and 27, fastened by means of screws 25 to the wings 24. The scouringknives 26 and 27 are arranged-oneclose behind the other and are kept at the desired distance from each other by a segmental spacing block or layer 28, of wood, india-rubber, caoutchouc, vulcanite fiber, or the like.y In order to find when fastening the scouring- Y knife carriers the required height rapidly and accurately, the wings 24 of the knives may be provided with segmental ledges 29, which serve as supports to the scouring-knife carriers 26 and 27.

In order to give to the knives 16 a circular motion, conical toothed wheels 30 are arranged on their bosses 23, which gear with conical toothed wheels 31 on the shafts 17.

IOO

The toothed wheels 31 sit, however, if viewed from in front or from above, Figs. 2, 3, and 6, partly on the left and partly on the right of the pins 18 for the knife-carriers 16 and so that all knife-carriers which from the center of the machine lie toward the left turn in the direction of the arrow :c in Fig. 6 no matter whether they are j ournaled in front of; or behind their driving-shaft 17, whereas the knives journaled on the right side of the machine turn in the opposite direction, therefore in the direction of the arrow y, Fig. 6. The shafts 17 must turn at a uniform speed. This is attained by toothed wheels 32 of the same number of teeth arranged at one end of the shafts and gearing with each other. Moreover, a smaller toothed wheel 33 on the main shaft 34,. journaled in' the fra-me ofk the machine gears withthetoothed wheel 32` of one of the shafts 117. The ratio ofv transmission` ini the construction shown in thedrawings is one to four..L this willbe stated. farther on. rlihe main shaft 34v may be provided with a fast and loose pulley 35 and 36y for the driving-belt and, moreover, with a fly-wheel 37, which serves at the same time as anhand-wheel.

Below each longitudinal row of knife-carriers 16 a broad. strap 38 is placed upon thel cushion 10', the ends of which stra.` may be screwed to the side Walls of the air-box 13, Figa 2'. Over these straps the fabric 11 tobe worked on is. fed: after being unwound from a beam or roller 39, journaled in the frame of the machine, and after passingover asmoothing-roller 40 beforezit arrives at the operatingplace. In the front part of thefmachine the fabric is- Wound upon a roller 41, journaledin. the blocks 42'. On the roller 41 rests a. roller 43'-, journaled, the same as the guide-roller 44, in the arms 46,.which swing on the pin 45y in the frame of the machine.

When the fabric has` been released by thev scouring-knives-,it must. be drawn forward a little in order that during the next o eration not exactly the same place is rubbe :by the scouringrknives. To. this end. there is arranged on oneof the pins-47 of the roller 4.1 a.

arms 53, to whichl the pressers- 52 are screwed,l may be arranged on a joint-frame 54 abovethe knife-carriers. The said frame has on both sides of the machinel downwardly-di.- rected sliding bars 55, moving in the j ournals 56- and 5,7' of the frame ofthe-machine and securing thereby a vertical up.- and-down.

movement of the frame 54.v Springs60, (only shownv in Fig. 2,) placedwith one end@ ony pins. 58 of thev frame 54 and hung with their The reason of other end into hooks 59, screwed to the bottom of the air-box 13, constantly endeavor to draw down the frame 54 with the pressers 52 upon the fabric; but the frame is at the same time supportedA on both sides by levers 61, movably joined to arms 62 of an axle 63, journaled in the frame of the machine and act upon bolts 64 ofthe frame 54. One arm 65 of the axle 63 is, moreover, actuated by the eccentric-rod' 66. which is moved' by means of the circular eccentric 67 on the main shaft 34. The axle 63 thus receives an oscillating mo tion, which is converted inteany upfand-down:

checkedy motion of the` lever 61;. Inl order that the pressers- 52' in their lowest position, are pressed down uponV the fabricy only under the action of the'spring 60, theflevers'll` are provided with a longitudinal' slit 68, through which the bolts 64l on the frame54 pass, Fig. 1. Since, as already said, the main shaft 34 drives the shafts 1:7 for the knifescarriers with a ratio. of. transmission of.4 one to' four..v

therefore when. no sco tiring-knife to uchesthe'l fabric. This position returns ateach quarter of a revolution of. the knife-carriers 16. From they oscillating movement of the axle 63. may at the same time be derived themovement of the lever 50 on: thel roller' 411.. For this purpose a lever-69 is loosely` arranged.` on the axle 63- by the sideof thel lever-arm 65, and this lever 69-is connected by ai drawing-rod 7 O-withthelever 50a -A cross-arm71` of the lever 69 catches behindtzhearm 65-,.so` that` the lever 69-must follow the movement. of the arm totheright, asv shown irl-Fig.. 1, and turn the lever 50;' but if the arm 65 swings back, the lever 69, under the actioniof,l for instance, a spring-72.', acting upon. the lever 50, only follows solfar as a pin 732on: the frame of the machine admits of.y

When inv this scouring-machine the knife-- carriers 1:6 get into'the workingpositiony accordingA to Fig. 6 the first scouringfknife 2.6A of the two-scouringknives26 and 2.7, follow-A ing one close behind the other, is the-first in all the knife-carriers 16, to touch the fabric 11, which is smoothly stretched out on. thestraps 38. The first scouring-knives 2.61iirst carry away withv themthe fabric, according" to;1 the elasticity of thel latter and.` alsov of the cushion 10. Duringthe first part of their movement thefirst scouring-knives 26=therefore stretch the fabric; Only after' thisrhas' been done the scouring action, properly speaking, of the first scouring-knivesZG-,comvmences. When. the knife-carriers thereuponl continue their rotary movement, the second scourng-knives 27 likewise touchy the fabric', but not in those places `which were-they points of contact for the knives2'61ontheir'conmk mencing to work, but more sidewise, asthe IOO IIO

fabric is still held stretched by the first scouring-knives 26. The second scouring-knives 27 therefore considerably hasten the scouring. They make it possible to distribute the threads of the warp more uniformly than single scouring-knives following each other at greater intervals.

If desired, the number of scouring-knives to immediately follow the first may be increased. Thus, for instance, Fig. 7 shows a modification in which three scouring-knives 27 follow the first scouring-knife 26 on each arm or wing 24 of the knife-carriers 16.

What I claim as my invention, and desire to secure by United States Letters Patent,

1. A scouring-machine for woven fabrics comprising a counter-pressure surface, a plurality of knife-carriers arranged in parallel rows, each of the said knife-carriers having groups of two or more scouring-knives, the said groups of scouring-knives being spaced apart a sufficient distance and the corresponding groups of scouring-knives of the said knife-carriers having uniform inclination toward the counter-pressure surface so as to permit the fabric passing over the counterpressure surface to be periodically fully relieved between the strokes of the corresponding groups of scouring-knives of all the knifecarriers, means for holding the fabric on the counter-pressure surface during the strokes of the groups of scouring-knives, and means for operating the knife-carriers.

2. A knife-carrier comprising a boss, having radial wings, and ledges, inner and outer knives seated against the ledges, spacingblocks located between the knives, and means` for securing the knives, blocks and radial wings together.

3. A knife-carrier comprising a boss, having radial wings, and segmental ledges, inner and outer knives seated against the ledges, segmental spacing-blocks located between the knives, and means for securing the knives, spacing-blocks and wings together.

4. A knife-carrier comprising a boss, having radial wings, and ledges, inner and outer knives and intermediate knives seated against the ledges, spacing-blocks located between the knives, and means for securing the knives, blocks and radial wings together.

In testimony whereof I afIiX my signature in presence of two witnesses.
